Secure the receiver in a vise (USE A RECEIVER BLOCK. DON'T CLAMP THE RECEIVER IN THE VISE DIRECTLY!!!!) The end of the buffer tube has wrench flats. It might be quite snug. Take care to not round off the wrench flats. When you reinstall the tube, be sure to us anti-sieze compound on the threads to prevent galling. Good Luck!

BTW, I used a strap wrnch on the buffer tube itself. I tried a wrench at the end, but it started maring it, so I went to Sears and bought a strap wrench. I also used the strap wrench to install the tele style buffer tube and nut.

Why not send the guy to the AR15 webpage that has the Military manual. That way he can download it (or use one of the other pages that Ed has provided), read it, and gain more knowledge about the AR15.www.ar15.com/articles/index.html?cat=11Of course I could be wrong....

The General Discussion Board is to the AR15.com forums as are Beanie Babies and Beef Jerky to Gun Shows. <img src=/images/smilies/smiley_crossbones.gi
